How may entropy be reversed?
Why do some people ask questions on the forums, after stating that they are not well read on the topic they asked about and then proceed to poorly argue with the answers someone took the time and effort to be helpful?
How is your finger?
a*d^x+e*b^x=c solve for x
Are friends electric?
How can we get more scientists, engineers and teachers in to government roles?
How can I inspire more people to learn?

In all seriousness, some of those I would really like to have the answers for.

The subject of burning questions reminds me of the opening stanza of The Love Song of J. Alfred Prufrock:

LET us go then, you and I,
When the evening is spread out against the sky
Like a patient etherized upon a table;
Let us go, through certain half-deserted streets,
The muttering retreats
Of restless nights in one-night cheap hotels
And sawdust restaurants with oyster-shells:
Streets that follow like a tedious argument
Of insidious intent
To lead you to an overwhelming question….
Oh, do not ask, “What is it?”
Let us go and make our visit.

How many questions do you have a burning desire to know the answer to? ask them here, you may go away unhappy though.

Let's see, I know how life arose on earth (from scratch basically), know why math describes Nature so well (cut from same cloth), why man and ape share 98% DNA but yet so different (catastrophe theory), how consciousness arises (emergence from non-linear dynamics), the purpose of life (none), if God exists (of course not), is there life outside earth (of course), and "why" the Universe got started (pre-existence encountered critical-point).

But I'm still puzzled by what causes life to go from simple to complex so I guess that's what I have left to know.
